Abstract
Highways are one of the main elements of the infrastructure and economy of any state. It is well known that the state and level of development of the country's highways directly affect the main economic indicators – the gross national product, the price level, budget revenues, the level of employment, and others. When developing multicomponent binders, as a rule, a systematic approach is used. New binders are considered complex systems consisting of subsystems or elements, each performing its functions. The elements in the system are not isolated from each other but grouped in such a way as to ensure the practicality of the entire system. It should be noted that any changes in a single element or replacing one element with another usually lead to a change in the properties of the entire system. The elements of the system are interconnected, and the more versatile the connections, the more effective the system is. The researcher's task is to correctly select the elements of the system, considering their properties and contribution to the system's overall structure. Of all types of metallurgical slags, blast furnace slags are the most widely used in the production of building materials due to their leading position in the overall balance, their ability to acquire hydraulic properties during rapid cooling, and others.
